Abstract

A propellant composition comprises a propellant solvent, a propellant base, and a plurality of metal nanoparticles. A powder or dried propellant composition is formed by removing at least a portion of the propellant solvent. The metal nanoparticles of the plurality of metal nanoparticles are nonionic. The plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration.
